To all wh om it may concern: I i

Beit known that ,I, WILLi M. P. WEBER, a citizen of the United States, residing at White Castle, in the parish of Iberville and Stateof Louisiana, have invented certain new and useful Improvements in Mechan ical Sugar Sprayers; and I dohereby declare the followingto be full, clear, and exactv description ofvlth e invention, such as will enable othersskilled in the art to which it appertains to make. and use the same.

The present invention relatesto improvements in mechanical sugar. sprayers and has i for its purpose to provide .for the washing of sugar in a centrifugal. e

Other objects .ofthe invention are to produce a device for purging the sugar crystals while in the centrifugal and just after the act of separationh'as taken place; to provide in conjunction with the centrifugal a spraying pipe adapted, to be .let down into the centrifugal without interfering with its continuous rotation, into which pipe water under pressure is sprayed through the sugar,

crystals; in providing in conjunction with the pipe. and a tank and connections to re ceive a supply of water and to place the water under appropriate pressure 'and' to furthermore provide for the introduction of steam forcleansingthe parts and to provide a compact, simple and inexpensivedevice for the purpose stated.

With the foregoing and other objects in view, the invention will be more fully described hereinafter, and will be more par- 7 tieularly pointed out in the claims appended hereto.

In the drawings, wherein like symbols refer to like or corresponding parts throughout the several views, w r

The figure is a side elevation, with parts.

shown in section of the improved 1 devices illustrated in conjunction with a centrifugal which is shown in vertical section.

Referring more particularly tothedrawings 1 designates a centrifugal-having the. rotary basket 2 in which the sugar crystals are indicated at 3. as arranged in a layer or zone against the wall of the basket by virtue of the centrifugal force. Assume that the molasses has just been separated and that the centrifugal is in readiness to discharge the sugar crystals.

The portion of the machine or standard 4: is adapted to receive a bracket arm 5 connected thereto as by a bolt or other fasteningjG passing through the angled end .of the bracket arm; and this bracketarm at its free, end is adapted to Through, this bushing extends slidably a,

pipe '9 having numerous perforations 10 therein which preferably extend in rows spaced angularly about the pipe and adapted to throw minute streams horizontally against the layer of sugar crystals 3 while the centrifugal 2 is rotated. The pipe 9 is adapted to extend within'a short distance of the base of the centrifugal and at its lower end is closed or blocked to avoid the escape of the wash water. At itsupper end the pipe telescopes over a supply pipe 11 of lesser diameter, there being a stuffing box 12 at the upper end, of the distributor pipe 9 to avoid leakage and to provide a tight joint. The gland nut 13 may be removed from time tov time to insert. fresh packing. The stuffing box 12 forms a suitable enlargement upon the upper end of the pipe to which to attach a relatively large and weighty handle 14 by which the distributor pipe may be raised to the position indicated in dotted lines. Here the handle is engaged with a hook 15 suspended from a collar 16 carried upon the horizontal pipe 17 which is connectedby theelbow 18 to the vertical supply pipe 11.

I Thebase ofthe supply pipe 11 which is open and in communication with the interior ofjthe distributor pipe 9 should be just above the uppermost of the perforationslO whensaid distributor pipe is inthe lower position. The horizontal pipe 17 may be of any suitable length and provided vided to either put the tank 22 in communication with the water supply or place the tank 22 in communication with the pipe 17. The tank carries connections 24 and 25 for the attachment of a glass gage tube 26 to show the condition within the tank and the tank will be supported suitably'for instance by a bracket 27 attached to the standard or frame 1 considerably above the bracket 5. At the top of-the tank is a sec-.

given case and the operation is as follows When the process of. separation in the centrifugal basket 2 is finished and the sugar crystals are in readiness to be washed, the

heavy handle 14 is disconnected from the, hook 15 and the distributor pipe 9 is allowed to descend through the bushing 7 until it arrives at a lower position within the centrifugal whereupon the lowerportion of the packing boX will abut upon the upper anged end of the bushing .7 and arrest a further downward movement. v handle 23 of the valve casing 21 ,is turned for instance in the position indicated to place the water supply in communication with the tank 22 and a suitable amount of water is allowed to enter the tank; the amount being shown by the gage 26. Subsequently the valve handle 29 of the upper casing 28 will be turned appropriatelyto permit the entrance of compressed air above the/water in the tank. flow down into the pipe 17 by shifting the valve handle 23 and the water will descend under considerable pressure through the vertical supply pipe 11 and into the distributor pipe. 9, issuing under force out of the minute perforations 10 in small jets or streams which impinge against the sugar crystals and purge the same. This action is allowed to go on for a period of time while the centrifugal is rotated, and in this way sugar crystals are tlioroughlywashed before being discharged. As soon as the washing opera tion' is over the distributor pipe 9 is lifted out of the centrifugal soas to avoid interference with future operations and it is held suspended by the engagement of the handle,

14 with the hook 15. The overflow 30 is opened and the tank is preferably never completely filled in order to leave a suitable spacefor the head of air abovethe water' When it is desired to clean the 1 parts, the air supply may be disconnected column.

and the steam supply coupled hereto and steam under pressure circulated throughout the system.

These operations are repeated from time The'water will then be allowed to to time and the device will be found very desirable as saving considerable time and pro viding for the effective purging of the sugar crystals. The handle 14: fits over the hook 15 and the hook may be slid along the horizontal pipe. Of course any arrangement of hook and handle may be used.

It is obvious that various changes and modifications may be made in the details of construction and design of the abovespecifically described embodiment of this invention without departing from the spirit thereof,

such changes and modifications being re, stricted only by'the scope of the following claims.

What is. claimed is 1. A mechanical sugar sprayer comprising .1I1 comblna'tion with a centrifugal machine having arotary basket, a bracket supported by the machine over the basket, a distributor pipe, having minute perforations arranged in rows, slidable through said bracket and The valve into the centrifugal, a stuffing box on' the upper end of said pipe adapted to arrest its movement before striking the bottom of the basket, a supply pipe fitting telescopically within said distributor pipe, said distributor pipe being movable upon said supply pipe,

a horizontal pipe connecting with said sup- ,ply pipe, a hook suspended from the horizontal pipe, a weighty handle carried by the stufling box and positioned to engage said I hook, and. a tank being in connection-with a source of watersupply and air under pressure supply communicating with said horizontal pipe.

2. A mechanical sugar sprayer comprising in combination with a centrifugal machine having a rotary basket, a bracket supported by the standard of the machine and overlying the inner part of the basket, a bushing in said bracket coaxial with the basket, a perforated distributor pipe of large diameter slidable through said'bushing into and out of the basket, a stuffing box onth'e upper end of said distributor pipe adapted to rest on said bushing and having the weighty handle adapted thereto, a supply pipe of relatively small diameter fitting within said distributor pipe, a horizontal pipe coupled to said supply pipe and'having a hook adapted to engage said handle, a tank supportedby said machine and being in connection with said horizontal pipefan overflow; for said tank, and upper andlower valves for the tank being in connection respectlvely w th source of compressed air, steamand water supplies. 2
